BACKGROUND

The field of the disclosure relates generally to apparatus and methodsfor brewing beverages from precursor particulates, and more particularlyto apparatus and methods for distributing liquid to the brew basket ofsuch apparatus.

Beverages brewers for making hot beverages such as coffee or teatypically have a brew basket into which precursor particulates such asground coffee or tea leaves are loaded (e.g., loosely, contained in afilter bag or pod, or other manner). The brewer also includes a liquiddelivery system having a heater, such as a CALROD heater or othercommonly used heating arrangement, and a reservoir containing liquid(e.g., water) to be heated by the heater and used in brewing thebeverage. In some conventional brewers, a riser tube, or up tube,directs heated liquid from the heater to a showerhead that ispositionable over the brew basket where the liquid exits the showerheadand flows into the brew basket for contact with the precursorparticulates. Existing showerheads typically include a large chamberwith one or more outlet openings in the bottom of the chamber so thatliquid flows into the large chamber and then vertically downward throughthe outlet openings.

In such an arrangement, an undesired amount of thermal energy istypically lost from the heated liquid as is flows into contact with arelatively large surface area of material in flowing along the liquiddelivery system, including into the relatively large showerhead chamber.Additionally, in directing the liquid to exit the showerhead verticallydownward, localized or otherwise relatively uneven distribution of theliquid onto the precursor particulates occurs. For example, irrespectiveof the flow rate of liquid into and out of the showerhead, the liquidflows straight downward onto the same spot within the brew basket.

Accordingly, there is a need for a beverage brewer and in particular ashowerhead for such a brewer, that reduces thermal loss (e.g., so as todeliver hotter liquid to the brew basket and/or to speed up brewingtime), and facilitates a uniform distribution of heated liquid from theshowerhead onto the precursor particulates in the brew basket.

DETAILED DESCRIPTION

With reference now to the drawings, and in particular to FIGS. 1 and 2,one embodiment of an apparatus for brewing beverages from precursorparticulates is schematically illustrated and generally indicated at100. The illustrated apparatus is suitably configured for brewing hotbeverages such as coffee or tea from precursor particulates such asground coffee beans or tea leaves. It is understood, however, that inother embodiments the apparatus 100 and the various components thereofmay be configured and/or used for making other beverages, and that theprecursor may be other than in the form of particulates (e.g., liquid,large solid material, etc.) and remain within the scope of thisinvention.

The illustrated apparatus 100 comprises a brew basket 140 supportable bysuitable support structure of the apparatus. The brew basket 140 may beremovable from the apparatus 100 for loading precursor particulatestherein, for emptying used particulates and for cleaning the basket. Inother embodiments, the brew basket 140 may be moveable relative to thesupport structure for loading and emptying of the brew basket. And instill other embodiments, the brew basket 140 may remain stationery inthe apparatus 100. The brew basket 140 is generally cup-shaped orfrusto-conical and has an upper rim 142 defining an open upper end ofthe basket through which precursor particulates are loaded into the brewbasket. It is contemplated that general construction of the brew basket140 may be of any suitable construction, such as without limitation, abasket that holds a separate paper or other filter (not shown) intowhich the precursor particles are loaded, a basket (not shown) that ismade in part of a filter material so that precursor particles are loadeddirectly into the basket, or a basket (not shown) that is itself areplaceable cartridge that holds pre-loaded precursor particles. Thebrew basket 140 may include a handle (not shown) to facilitate thehandling of the brew basket 140 by a user. The brew basket 140 may beconstructed from any suitable material, such as metal, glass, ceramic,and/or plastic, that enables the apparatus 100 to function as describedherein.

The apparatus 100 further includes a reservoir 170 supported by aplatform 195 and in communication with a heating system (not shown)located inside the platform. Alternatively, the heating unit may belocated within the reservoir 170 or remotely from the reservoir. It isalso contemplated that the reservoir 170 or other suitable source ofliquid may be located remotely from the apparatus 100, by itself oralong with the heating unit, without departing from the scope of thisdisclosure. The heating unit may be an electric heating unit such as aCALROD heating unit, or any other suitable heating system that enablesthe apparatus 100 to function as described herein. The reservoir 170 isin suitable fluid communication with the heating unit to deliver liquid(e.g., water) to the heating unit. The reservoir 170 may have anysuitable volume capacity. In some embodiments, the user may manuallypour, without limitation, water or some other suitable liquid into thereservoir 170. Alternatively, the reservoir 170 may be connected to aliquid (e.g., water) source whereby liquid is introduced by action ofthe user, or introduced automatically into the reservoir 170 wheneverthe watermark therein falls below a predetermined threshold. In someembodiments, the apparatus 100 may be connected to a power outlet (notshown) via a power cord (not shown). Alternatively, or additionally, theapparatus 100 may be powered by a battery (not shown) or by any otherpower source that enables the apparatus 100 to function as describedherein.

Still referring to FIGS. 1 and 2, a container 150 is seated on a base160, which may be heated to keep the brewed beverage warm or is unheatedand simply functions to protect the surface on which the apparatus 100sits from potential damage. The illustrated base 160 includes a seat 165inset in the upper surface of the base 160 to facilitate properalignment and positioning of the container 150 on the base 160. Thecontainer 150 may comprise any suitable size and shape, such as for asingle serving or multiple servings. While not shown herein, it isunderstood that the apparatus 100 may further include a housing or otherguard structure enclosing all or some of the components of theapparatus. A control panel, display monitor, actuation button, and/orcables for connecting to a power source, etc. may also be included onthe apparatus 100.

The apparatus 100 further comprises a liquid delivery system 185 fordelivering heated liquid to the precursor particulates disposed in thebrew basket 140. In the illustrated embodiment of FIG. 2, the liquiddelivery system includes an up-tube (or riser tube) 180 disposed in thereservoir 170 for receiving heated liquid from the reservoir, and ashowerhead assembly 120 connected to the up-tube in flow communicationtherewith for receiving heated liquid from the up-tube and directing theheated liquid onto the precursor particulates in the brew basket 140. Asillustrated in FIG. 1, the up-tube 180 includes a suitable elbow 188that redirects liquid flowing up through the up-tube about a 90-degreebend. The showerhead assembly 120 includes a connector 210 having anopen end for connection to the elbow 188 in flow communication therewithto receive liquid from the up-tube into the showerhead assembly. Theopposite end of the connector 210 is closed. Various parts of the liquiddelivery system 185 may be fabricated from one or more suitablematerials that minimize the amount of thermal loss. Specifically, duringthe process of transporting hot liquid through the liquid deliverysystem 185, thermal loss of the hot liquid may be related at least inpart to the materials that define the surfaces over which the heatedliquid flows along the liquid delivery system 185. To minimize theamount of thermal energy transferred from the hot liquid to thesesurfaces, the amount of surface over which the heated liquid flowsbefore dispensing into the basket should be minimized, while thematerials contacted by the heated liquid are still sufficient towithstand the operating temperatures of the apparatus 100. In someembodiments, components of the liquid delivery system 185 are fabricatedfrom polypropylene. Alternatively, another type of material may be usedthat enables the apparatus 100 to function as described herein.

A showerhead 230 (FIG. 2) of the showerhead assembly 120 is pivotallymounted on the connector 210 in flow communication with the open end ofthe connector for receiving liquid from the up-tube into the showerheadvia the connector. The showerhead 230 in accordance with one embodimentmay be connected to the lid of the apparatus 100 for closing off accessto the brew basket 140 during operation. The lid is pivotal relative tothe apparatus 100 between an opened position, which provides access tothe brew basket 140, such as for loading or unloading the filter 130 andprecursor particulates into the basket, and a closed position in whichaccess to the brew basket is closed. The showerhead 230 pivots about theconnector 210 conjointly with the lid such that when the lid is closedthe showerhead is positioned at least in part over the precursorparticles.

More particularly, in the illustrated embodiment of FIG. 2 when the lidis closed the showerhead 230 is positioned at least in part above theentire brew basket 140, such as by a predetermined height above the rim142 of the basket. This height may be any suitable height that enablesthe apparatus 100 to operate as described herein. For example, theheight of the showerhead 230 above the brew basket 140 may be determinedsuch that liquid distributed by the showerhead into the basket reachesthe sidewalls of the basket or at least transversely outer portions ofthe particulates in the basket. It is understood, however, that in otherembodiments all or part of the showerhead 230 may be disposed at thelevel of the rim 142 of the brew basket 140, or even below the rim ofthe brew basket, as long as the showerhead is disposed above the levelof the precursor particulates contained in the brew basket.

With reference to FIGS. 3 and 4, the showerhead 230 is a generallyelongate tube 232 having an open proximal end 234 connected to theconnector 210 and a closed distal or free end 236. The tube 232 of theillustrated embodiment is suitably circular in cross-section. In otherembodiments, the tube 232 may be of another suitable cross-section suchas, without limitation, square, hexagonal, triangular or other suitableshape. The tube 232 according to one embodiment has a length from itsproximal end 234 to its distal end 236. The tube 232 also has an averageinner cross-sectional area along its length in the range of about 25 mm²to about 45 mm² and in one particular embodiment it is about 34 mm². Therelatively small cross-sectional area facilitates a reduced loss ofthermal energy as heated liquid flows through the tube 232.

The thickness of the tube 232, and hence an outer surface area of thetube may vary over its length from the proximal end 234 to the distalend 236 thereof. The outer surface area is thus determined as theaverage outer circumference of the tube 232 multiplied by the length ofthe tube. In one embodiment, the outer surface area of the tube 232 isin the range of about 3,000 mm² to about 3,500 mm², and in oneparticular embodiment it is about 3,335 mm². This also provides arelatively low mass of the showerhead, i.e., the tube 232. For example,in the illustrated embodiment the mass of the tube 232 along its lengthis about 3 grams. A relatively lower mass of the tube 232 facilitates areduced loss of thermal energy as heated liquid flows through the tube.

As seen best in FIG. 4, a plurality of outlet openings 240 are formed inthe tube 232 intermediate the proximal and the distal ends 234, 236 ofthe tube. In the illustrated embodiment, eight such outlet openings 240are formed in the tube 232, and more particularly four pairs of outletopenings are formed in the tube with each pair of outlet openings beingspaced longitudinally from the other pairs of outlet openings. A flowdirection of liquid through the tube 232 is indicated by the directionarrow in FIG. 4 and is generally from the proximal end 234 of the tubetoward the distal end 236. It is understood that the tube 232 may havemore than eight outlet openings, or less than eight outlet openings, andremain within the scope of this disclosure.

As illustrated in FIG. 4, each pair of outlet openings 240 is arrangedwith one outlet opening located on one side of a vertical centerline ofthe tube 232 and the other outlet located on the opposite side of thevertical centerline of the tube. The circumferential or angular spacingbetween the two outlet openings 240 may vary among the different pairsof outlet openings as in the embodiment of FIG. 4, or the spacing may bethe same for each pair of outlet openings. For example, in theillustrated embodiment the first and last pairs of outlet openings 240along the flow direction of liquid through the tube 232 is configuredwith the openings relatively closer together than the middle two pairsof outlet openings. This arrangement accounts for the transverse spacingbetween the tube 232 and the sidewall of brew basket being smaller wherethe first and last pairs of the outlet openings 240 are located when thetube 232 spans the basket 140. Cross-sections of the tube at one of themiddle pair of outlet openings 240 and at the last pair of outletopenings are illustrated in FIGS. 5 and 6, respectively. The outletopenings 240 of FIG. 5 are located on the tube 232 at respective angles410, 420 relative to vertical of −45 degrees and 45 degrees, while theoutlet openings of FIG. 6 are located on the tube at respective angles510, 520 relative to vertical of −30 degrees and 30 degrees. However,the angular locations of the outlet openings 240 in the tube 232 may beother than as illustrated, such as any suitably angle 410, 420, 510, 520less than about 90 agrees relative to vertical, more suitably in therange of about 10 degrees to 80 degrees, even more suitably about 15degrees to about 60 degrees, and still more suitably about 30 degrees toabout 45 degrees.

The outlet openings 240 illustrated in FIGS. 3 and 4 are suitablycircular. In alternative embodiments, one or more of the outlet openings240 may be other than circular, such as hexagonal, oval, triangular orany other shape that enables the apparatus 100 to function as describedherein. The outlet openings 240 are suitably sized in cross-section toinhibit mineral or residue build-up at the openings. For example, in oneembodiment the outlet openings 240 may each have a diameter in a rangeof about 0.01 inches to about 0.50 inches (in.); more suitably about0.05 in. to about 0.40 in.; even more suitably about 0.10 in. to about0.30 in; and yet more suitably about 0.11 in. to about 0.20 in.

FIG. 4 illustrates the showerhead 230 with the tube 232 positioned abovethe upper rim 142 of the brew basket 140. The view of FIG. 4 is thuslooking upward at the rim 142 of the basket, with the rim shownschematically and the rest of the brew basket omitted. While theillustrated brew basket 140 is generally circular in cross-section, itis understood that in other embodiments the brew basket may be shaped incross-section as a square, ellipse, triangle or other suitable shape andremain within the scope of this disclosure. The tube 232 as seen in FIG.4 is suitably sized in length such that at least the extent of the tubehaving the outlet openings 240 spans diametrically across a substantialportion of the brew basket 140. While in the illustrated embodiment theclosed distal end of the tube 232 is disposed above the brew basket 140,it is contemplated that in other embodiments the distal end of the tubemay be disposed beyond the brew basket 140 as long as the outletopenings are positioned relative to the brew basket to direct liquidonto the precursor particulates in the brew basket.

The tube 232 is sized in length and positioned above the brew basket 140such that, in the flow direction of liquid through the tube 232, thefirst pair of outlet openings is nearer to the sidewall of the brewbasket 140 than the last pair of outlet openings. This arrangementaccounts for the forward velocity of liquid that exits the outletopenings in the flow direction. For example, as illustrated in FIG. 4 bythe dashed exit flow paths 241, liquid exiting the outlet openings 240has some tendency to continue in part in the flow direction of theliquid. Accordingly, the outlet openings 240 are thus located along thetube 232 relative to the brew basket so as to be generally upstream ofthe desired reach of the liquid into the brew basket. In otherembodiments, the outlet openings 240 may be located along the tube 232relative to the brew basket 140 in a more uniform spacing across theextent of the brew basket.

In operation of the apparatus 100, the heating unit 190 receives liquidfrom the reservoir 170 and heats the liquid to a boil, thus generatingbubbles, which increase and become more excited as the temperatureinside the heating unit rises. The bubbling creates an expansion ofvolume that forces liquid upward through the up-tube 180 to theshowerhead assembly 120. The heated liquid flows into the showerheadassembly 120 and more particularly through the tube 232 in the flowdirection toward the distal end of the tube. The liquid exits the tube232 through the outlet openings 240 into the brew basket 140 and ontothe precursor particulates. Because the outlet openings 240 are angledrelative to vertical, the liquid generally flows outward of the outletopenings other than vertically downward. It is understood, however, thatone or more downward facing outlet openings may also be included in thetube to allow some of the liquid to exit the tube 232 verticallydownward.

During a brewing cycle, liquid is delivered from the heating unit upthrough the up-tube 180 to the showerhead assembly 120 generally inpulses. That is, as heated liquid flows from the heating unit to theshowerhead assembly 120, cooler liquid from the reservoir 170 flows intothe heating unit. Thus, there is a slight delay in the flow ofadditional heated liquid from the heating unit to the showerheadassembly as the cooler liquid is heated. This results in the liquidbeing delivered to the showerhead assembly 120 in what appears to bepulses of liquid. These pulses may vary in pressure, volume and/or flowrate to the showerhead assembly. For pulses that are lower in pressure,volume and/or flow rate, the heated liquid flows less forcefully orrapidly into the showerhead 230 and thus out of the outlet openings 240.As a result, the heated liquid does not flow very far outward away fromthe tube, and in some instances it may dribble generally downward overthe tube below the outlet openings 240 and then fall downward onto theprecursor particulates. For pulses that are higher in pressure, volumeand/or flow rate, the heated liquid flows more forcefully or rapidlyinto the showerhead 230 and upon exiting the outlet openings 240 of thetube 232 the liquid flows (e.g., at least in part transversely) outwardaway from the tube such as illustrated in FIG. 4. Thus, over the courseof a brewing cycle, the precursor particulates are more uniformly wetwith heated liquid.

FIGS. 7 and 8 illustrate another embodiment of a showerhead assembly 320suitable for use with the apparatus 100 of FIG. 1 or other suitablebrewing apparatus. The showerhead assembly 320 is similar to theshowerhead assembly 120 of FIGS. 3-6 in comprising a connector 410 andshowerhead 430 that is a generally elongate tube 432 having an openproximal end 434 connected to the connector 410 and a closed distal orfree end 436. The tube 432 is suitably circular in cross-section. Inother embodiments the tube 432 may be of another suitable cross-sectionsuch as, without limitation, square, hexagonal, triangular or othersuitable shape. In this embodiment, the showerhead 430 is configured asa loop to extend generally in accordance with the circumference of thebrew basket 340. In the illustrated embodiment of FIG. 7, the loop shapeof the showerhead 430 is generally oval or elliptical. In otherembodiments the loop shape of the showerhead 430 may be circular,hexagonal or other suitable shape and remain within the scope of thisdisclosure.

With continued reference to FIG. 7, a plurality of outlet openings 440are formed in the tube 432 in spaced relationship with each other alongthe circumference of the loop segment of the tube. In the illustratedembodiment, eight such outlet openings 440 are formed in the tube 432. Aflow direction of liquid through the tube 432 is indicated by thedirection arrow in FIG. 7 and is generally from the proximal end 434 ofthe tube toward the distal end 436. It is understood that the tube 432may have more than eight outlet openings, or less than eight outletopenings, and remain within the scope of this disclosure. The outletopenings 440 are illustrated as being equally spaced along thecircumference of the tube 432. In other embodiments, however, thespacing being outlet openings 440 may be non-uniform without departingfrom the scope of this disclosure.

In this embodiment, the outlet openings 440 are each located on theinner side of a vertical centerline of the tube, e.g., so as to beangled in part transversely inward of the brew basket. FIGS. 9-16 arecross-sections taken through the tube 432 at the location of eachrespective outlet opening 440 along the flow direction of liquid throughthe tube. The angle of each respective outlet opening 440 relative tovertical can vary among the outlet openings, as in the illustratedembodiment. For example, In FIGS. 9 and 11 the respective outlet opening440 is located at an angle 810, 1010 of 65.4 degrees relative to thevertical centerline 530. In FIGS. 10, 12 and 14 the respective outletopening 440 is located at an angle 910, 1110, 1310 of 75.3 degreesrelative to the vertical centerline 530. In FIG. 13, the outlet opening440 is located at an angle 1210 85.4 degrees relative to the verticalcenterline 530. In FIG. 15 the outlet opening 440 is located at an angle1410 of 68.0 degrees relative to the vertical centerline 530. And inFIG. 16 the outlet opening 440 is located at an angle 1510 of 73.6degrees relative to the vertical centerline 530. However, the angularlocations of the outlet openings 440 in the tube 432 may be other thanas illustrated, such as any suitably angle less than about 90 agreesrelative to vertical.

In operation, during a brewing cycle, liquid is delivered from theheating unit up through the up-tube 180 to the showerhead 430 generallyin pulses. That is, as heated liquid flows from the heating unit to theshowerhead 430, cooler liquid from the reservoir 170 flows into theheating unit. Thus, there is a slight delay in the flow of additionalheated liquid from the heating unit to the showerhead 430 as the coolerliquid is heated. This results in the liquid being delivered to theshowerhead 430 in what appears to be pulses of liquid. These pulses mayvary in pressure, volume and/or flow rate to the showerhead assembly.For pulses that are lower in pressure, volume and/or flow rate, theheated liquid flows less forcefully or rapidly into the showerhead 430and thus out of the outlet openings 440. As a result, the heated liquiddoes not flow very far outward away from the tube, and in some instancesit may dribble generally downward over the tube below the outletopenings 440 and then fall downward onto the precursor particulates. Forpulses that are higher in pressure, volume and/or flow rate, the heatedliquid flows more forcefully or rapidly into the showerhead 430 and uponexiting the outlet openings 440 of the tube 432 the liquid flows (e.g.,at least in part transversely) outward away from the tube as illustratedby the dashed line flow paths in FIG. 7. Thus, over the course of abrewing cycle, the precursor particulates are more uniformly wet withheated liquid. Because the outlet openings 440 are angled relative tovertical, the liquid generally flows outward of the outlet openings 440other than vertically downward, and more particularly inward toward thecenter of the brew basket 340. It is understood, however, that one ormore downward facing outlet openings 440 may also be included in thetube 432 to allow some of the liquid to exit the tube verticallydownward onto the precursor particulates.

 14. A method of brewing abeverage from precursor particulates, the method comprising: loadingprecursor particulates into a brewing basket; delivering liquid in aflow direction through a showerhead disposed above at least a portion ofthe brew basket; and directing liquid to flow out of the showerheadthrough a plurality of outlet openings of the showerhead into the brewbasket for flow over the precursor particulates, at least one of theoutlet openings being oriented to direct liquid out of the showerheadother than vertically downward into the brew basket.
 15. The method ofclaim 14 wherein a plurality of said outlet openings is oriented todirect liquid out of the showerhead other than vertically downward intothe brew basket.
 16. The method of claim 14 wherein the showerhead isdisposed at least in part centrally of the brew basket, the step ofdirecting liquid to flow out of the showerhead into the brew basketcomprising directing liquid to flow out of the showerhead at least intwo different directions each being other than vertically down into thebrew basket.
 17. The method of claim 16 wherein the at least twodifferent directions comprise a first angle relative to verticallydownward, and a second angle relative to vertically downward, the firstangle being in the range of about 15 degrees to about 60 degrees, thesecond angle being in the range of about −15 degrees to about −60degrees.
 18. The method of claim 16 wherein the first angle is in therange of about 30 degrees to about 45 degrees and the second angle is inthe range of about −30 degrees to about −45 degrees.
 19. The method ofclaim 14 wherein the showerhead extends circumferentially one of aboveand within the brew basket, the step of directing liquid to flow out ofthe showerhead into the brew basket comprising directing liquid to flowout of the showerhead at least in part transversely inward of the brewbasket.
 20. The method of claim 14 wherein the step of delivering liquidin a flow direction through a showerhead disposed above at least aportion of the brew basket comprises varying the flow rate of liquidthrough the showerhead such that a transverse distance that liquid flowsoutward from the at least one of the outlet openings into the brewbasket varies with the flow rate of liquid delivered through theshowerhead.
